You don't have to look like Brad Pitt to start building your self confidence. 3  3. Exercise regularly. Part of taking care of yourself is getting exercise.  4. Sleep well.
Stationary Waves. Stationary or standing waves are formed in a medium when two waves having equal amplitude and frequency moving in opposite directions along the same line, interfere in a confined space. Generally, such waves are formed by the superposition of a forward wave and the reflected wave. Both longitudinal and transverse types of waves can form a stationary wave. When reflection occurs at a free end, there is no reversal of phase. i.e., a crest returns as a crest and a trough as a trough.
Transverse waves are wave in which the vibrations of the particles or medium in which the wave travels are at right angles to the direction in which the wave travels. Water waves are an example of transverse waves. These can be observed in a ripple tank. The animation below shows transverse waves created in a ripple tank. From the above animation it can be seen that the rubber duck only moves up and down whilst the energy of the wave moves along the tank.
